I. ADMINISTRATIONThe use of all x-ray producing equipment on FAU’s campuses falls under the jurisdictionof the RSO (Radiation Safety Officer) and the RSC (Radiation Safety Committee). All x-ray producing equipment must be registered with the RSO and the Florida Department ofHealth, Bureau of Radiation Control (BRC). The use of analytical x-ray equipment isregulated by Florida Administrative Code 64E-5.701-5.704. All purchases and/ortransfers of x-ray producing equipment must receive prior approval from the RSO andRSC.II. TRAININGAll users of x-ray producing devices are required to participate in FAU Radiation SafetyTraining for x-ray Users. New users must enroll in the required initial training course.Sessions are offered on an as needed basis. Please contact the RSO to register for thetraining. All users are also required to complete annual refresher training which isavailable in a web-based format. If you have received training at another institutionbefore coming to FAU this training must be documented with the RSO.III. SECURITYAll x-ray producing equipment will be operated only by trained faculty, staff, or students.No x-ray producing equipment will be left operating unattended without prior approvalfrom the RSO. If approved to do so by the RSO, the laboratory entrance/exit doors mustbe locked while the machine is operating. All x-ray producing equipment will be securedwhen not in use in such a manner that it cannot be used by untrained, unauthorizedworkers or members of the public, either knowingly or unknowingly. This must be doneby either removing keys necessary to operate the equipment or locking the room in whichthe equipment is located. All x-ray use laboratories and x-ray equipment must be labeledwith appropriate warning signs to alert others as to the possible dangers associated withuse of the device.IV. RADIATION PROTECTION PROGRAMA. ALARAIt is this university’s intent to operate all x-ray producing equipment in such a manner asto keep doses, to workers and members of the public, As Low As ReasonablyAchievable.X-Ray Safety Manual (7/06) 1
B. POSTINGSThe FAU Radiation Protection Program for the Safe Use of x-ray ProducingEquipment (Appendix A) must be posted near each x-ray device. This protection planshould be known, understood, and followed by each individual operating an x-rayproducing device. The Notice to Employees and Worker’s Compensation Proceduresinformation (in Appendix B) must also be posted next to each x-ray producing device.All x-ray equipment should be labeled as outlined in FAC 64E-5.701 (4) and summarizedas follows: 1) “CAUTION-HIGH INTENSITY X-RAY BEAM” or similar wording, on the x-ray source housing 2) “CAUTION RADIATION- THIS EQUIPMENT PRODUCES RADIATION WHEN ENERGIZED” or similar wording near any switch that energizes an x-ray tube if the radiation source is an x-ray tube. 3) An easily visible, fail-safe warning light labeled with the words “X-RAY ON” or similar wording located near any switch that energizes an x-ray tube. This warning light should be illuminated only when the tube is energized.C. RADIATION PROTECTION PROCEDURES 1) Understand and apply the three cardinal principles of radiation protection and control: time, distance, and shielding. 2) Avoid exposure to the primary beam. 3) Avoid holding the patient or object to be imaged. 4) Always wear a personal dosimetry device. 5) Analyze the hazards of each job in advance. 6) Provide safeguards against foreseeable accidents. 7) Use protective devices and planned emergency procedures when accidents happen.D. GUIDELINES FOR USING RADIATION-PRODUCING MACHINESX-Ray Safety Manual (7/06) 2
1) Before working with any radiation-producing machine, adequately trained personnel must be familiar with the work that is to be done and the safety precautions to be taken. 2) Written operating instructions and safety procedures must be available to personnel before operating the machines. 3) Visitors in areas where radiation-producing machines are used must be supervised by the equipment operator. 4) Radiation-producing machines must not be left unattended while operating unless the operator has received prior approval to do so by the RSO. If approved, the laboratory entrance/exit doors must be locked while the machine is operating. 5) Structural shielding requirements for any new installation, or an existing one in which changes are to be made, must be reviewed by the RSO before the machine is to be used. 6) If the safe use of the radiation-producing machine depends on the mechanical set-up of the unit or on technique factors, then these restrictions must be rigidly followed. 7) Shutter mechanisms and interlocks must not be tampered with or defeated under any circumstances. 8) All warning lights must be "fail safe". 9) A manually reset cumulative timing device must be used which will either indicate elapsed time or turn off the machine when the total exposure reaches a certain previously determined limit. 10) All radiation-producing equipment must be properly maintained. Attempts to "fix" equipment should only be made by properly trained technical staff. 11) All x-ray machines must be registered with the State of Florida BRC and maintained on inventory with the RSO. 12) Instrumentation which contains a radioactive calibration source must be maintained on inventory with the RSO.E. COMMENTS FOR USERS OF X-RAY DIFFRACTION UNITSX-Ray Safety Manual (7/06) 3
X-ray diffraction units are designed for routine analytical work and, in theory, do notpresent a radiation hazard to the user if simple precautions are observed. However, theymake use of extremely high-intensity primary beams. Although the primary beam mayhave a diameter on the order of a centimeter, it can produce a severe and permanentlocal injury from only momentary irradiations of the body. The primary beamintensities can range from 50 to 400,000 R/minute depending upon the scatter distancefrom the x-ray source.The greatest risk of acute accidental exposure occurs during sample manipulation by theprimary beam. Exposure rates of 10,000 R/sec can exist at the tube housing port. Skinreddening can occur after an exposure of only 0.3 seconds, and in 1 second, severe andpermanent injury could occur. The fingers are the parts of the body most likely toreceive these high exposures.Modern x-ray diffraction units incorporate shielding and safety features to prevent bothacute and local accidental exposures and chronic long-term exposures. Operators mustbe fully aware of the protective devices incorporated into their machines and thepossibilities for failure or malfunction of the safety devices. Operators may be assigneda personal radiation monitoring dosimeter to record their exposure when operating x-raydiffraction units if they have the potential of receiving 10% of the maximum annualoccupational dose limit.X-ray diffraction units must be surveyed by The State of Florida BRC at least once peryear. The RSO must also survey each unit at least once per year and whenever theequipment is relocated or modified. The RSO is also responsible for the following: • All of the posting requirements listed in part B of this section apply to x-ray diffraction units. • All analytical x-ray equipment must be registered with the Environmental Health and Safety Office. • Shutters should be used that cannot remain open unless a collimator is in position. Shutter interlocks should be used to cut off the beam when samples are changed. • No repair, cleaning work on shutters and shielding materials, or non- routine work that could result in exposure to the primary beam will be allowed unless it has been positively ascertained that the x-ray tube has been completely de-energized. • Everyone working with analytical x-ray equipment must receive prior approval from the RSO and the RSC and pass the Radiation Safety Training Course for x-ray Users.F. COMMENTS FOR USERS OF DIAGNOSTIC X-RAY UNITSX-Ray Safety Manual (7/06) 4
Workers using diagnostic x-ray devices (C-arms, dental, medical, etc.) must be sure towear the appropriate personal protective equipment (PPE) when operating the device.All diagnostic x-ray units must be surveyed by The State of Florida BRC at least once peryear. The RSO must also survey each unit at least once per year and whenever theequipment is relocated or modified. The RSO will evaluate the hazards associated withthe device and establish protection guidelines for safe use of the device. AppropriatePPE recommendations will be made for each type of device and may include thefollowing: safety glasses, radiation dosimeter, lead aprons, etc. If you are assigned apersonal radiation dosimeter, you must wear it at all times when operating the x-raydevice. Dosimeters will be assigned to individuals with the potential to receive 10% ofthe maximum annual occupational dose limit. If you are unsure of what PPE to wearwhen operating your x-ray device contact the RSO.The following guidelines must be followed by all diagnostic x-ray operators to ensuremaximum protection for both the operator and the patient: • A licensed Medical Doctor or Doctor of Veterinary Medicine will specifically and individually order all exposures. • Humans must not be exposed for training, demonstration, or other non-healing art purposes. Except for Student Health Services, Florida Atlantic University is not licensed for exposure of humans. • Appropriate measures must be used to keep patient exposure at a minimum, while still obtaining the necessary diagnostic information. • The operators must stand behind the protective barrier at the controls (if applicable) and wear personal dosimeters (if assigned) during the exposure. • Only individuals required for the radiographic procedure are to be in the room during the exposure. • Access to the x-ray room should be secured during the exposure. • Everyone working with diagnostic x-ray equipment must receive prior approval from the RSO and the RSC and pass the Radiation Safety Training Course for x-ray Users.
